Unit 8: When Chemicals Meet Water—The Properties of Solutions


Unit Overview

Solutions are all around us, from the air we breathe to the blood in our veins to the steel frames of many buildings. While solutions don't have to be liquids, aqueous, or water based, solutions are fundamental to life and common in inorganic chemistry: The majority of biochemical reactions happen in aqueous solutions. The formation of a solution depends upon the interactions between the solute (the substance that gets dissolved) and the solvent (the substance that does the dissolving); in turn, the interactions of solute and solvent are heavily influenced by their concentrations, temperature, and pressure. Solution chemistry is behind the extraction of materials for a variety of applications, for example, making a great cup of coffee.
